Paradox Interactive has brought about a launch trailer for Hearts of Iron III: Their Finest Hour. An expansion to their best-selling World War II strategy title, Their Finest Hour will feature new units, new tools and new ways to muck about with the map setup.

That’s not including the new missions. You reportedly “break into Fortress Europe with elite troopers, island hop across the Pacific with new amphibious war technologies, draft and share your plan for winning a land war in Asia” and much more. Check it out today for $19.99 USD.
